git: rebase between init commit to specified commit

Question

How do I rebase between commits:

Lets say I want to rebase between init and commit 3 (squash these commits together)

Lets say i have

commit 5
commit 4
commit 3
commit 2
commit 1
commit init

If I do

git rebase -i commit 3 

I get this:

pick commit 3
pick commit 4
pick commit 5

Then when i do

squash commit 3
pick commit 4
pick commit 5

And I execute the action, I get this:

commit 3
commit 2
commit 1
commit init

Instead of what i want.

How do I squash commit init<---->commit 3, instead of commit 3<----->commit 5

Thanks in advance.

Jenia.

Answer 1

Do

git rebase -i --root

Git will drop you into an editor with

pick commitinit
pick commit2
pick commit3
pick commit4
pick commit5

then just change it to

pick commitinit
squash commit2
squash commit3
pick commit4
pick commit5
